Mizrahi going ‘Undressed’

Mantello, Stone join legit show

Isaac Mizrahi has finally settled on a name for his one-man musical. Playing off the title of his 1995 documentary “Unzipped,” he’s calling the legit show “Undressed.”

Joe Mantello replaces playwright-director Moises Kaufman (“Gross Indecency”) as helmer on the musical, which stars Mizrahi as himself. And David Stone has joined the show’s original producing team, Dori Berinstein and Susan Quint Gallin.

According to sources close to the production, Mizrahi will sing but not play the piano in “Undressed.” The latter artistic endeavor caused the designer, whose fashion line went belly up a year ago, much concern when docu director Douglas Keeve refused to cut Mizrahi’s rendition of Debussy’s “Clair de Lune” from “Unzipped.” Mizrahi didn’t feel his piano-playing was up to Hollywood standards; apparently, he feels his singing will be up to Off-Broadway standards.

The producers are looking for a January-February opening, pending an available theater. Beyond the current theater crunch, there is also the problem of Mantello’s increasingly busy sked. Before year’s end, he will direct another one-person show, Marc Wolf in his play “Another American: Asking and Telling,” about gays in the military, at the New Group.

In November, the Blue Light Theater Co. presents the world premiere of Daniel Goldfarb’s “Adam Baum and the Jew Movie,” about a Hollywood movie mogul, with Mantello directing. In February, the helmer will reprise his original Gotham staging of Neil LaBute’s “Bash” at the Almeida Theater in London.
